i have had lots and lots of pain there for 12 years or so, for no apparent reason. i have been to see all sorts of medical practitioners in that time, but any relief was always temporary. finally i was referred to a top top shoulder specialist who thinks it is what i have suspected for some time- arthritis.i have an mri scan on tuesdya to confirm this. he said there are things you can do t sort it out. i was too scared to ask what these are. i guess it depends what type of arthritis it is. anyone else got any experience of this?
